The Wireless TV Connect from HP is being marketed primarily as a way to get 1080p video from your laptop to your TV without the need for wires. Realistically though, the device can pull HD video from any source you've got.

HP's wireless HD solution can be powered by USB or a standard wall plug
and is capable of sending an HD video signal up to five meters. In
addition to 1080p video, you'll be getting 7.1 channel audio as well –
it seems like the perfect solution for your wireless woes.

The Wireless TV Connect has a response time of just one millisecond, so
you can use it for a variety of applications – including gaming –
without having to worry about delay.
